If the perpendicular bisector of one side of a triangle goes through the opposite vertex, then is the triangle ( sometimes, alwa

ys, or never) isosceles

It is always isosceles because it can be proved as follows:

The perpendicular bisector dissects the triangle into two, and it is the common side.  Then each side of the bisector is 90 degrees, and the bisected to two equal sides, so the two dissected triangles are congruent, hence the original triangle is isosceles.

Jerry deposits $80.00 into a new savings account.
Temka [501]

Answer:

91.80

Step-by-step explanation:

You can get this simple answer by finding the number value of 3.5%, which would be .035. Since you are trying to go up by 3.5%, you can take the .035 and add a 1 onto it to signify that you are not losing any money, you are gaining it or staying the same at least. If you want to see how much money he will have after 4 years, just multiply 80 by 1.035, then take the answer and multiply it by 1.035 again. Then take the answer and do it again to signify the third year, and then take that answer and multiply it by 1.035 to signify the fourth and final year. You will see that he gets about $91.80 after 4 years.

Find how many numbers greater than 400,000 can be made using all the digits of 416566​
Mandarinka [93]

Answer:

20

Step-by-step explanation:

You have to fill in 6 slots _ _ _ _ _ _.

Since first digit must be 4, there is only 1 way to fill in the 1st slot.

with the 5 slots, we fill in the 6s first, 3 of them.

So we have 5 options and 3 items to fill, (5 choose 3).

Then 2 ways to fill 1 and 1 way to fill 5. (It doesn't matter if you pick 5 or 1 first).

So it becomes (5C3) * (2C1) *(1C1)

= 1 * 5!/(3!)(5-3)! * (2) * 1

= 20

Assume a color display using 8 bits for each of the primary colors (red, green, blue) per pixel and a frame size of 1280 × 1024.
elixir [45]

-8bits is equivalent yo 1 byte

-bit is(0 or 1)

So each pixel requires 3 bytes

Primary colors are RGB(red,green and blue),so each color represent one byte.

The frame size is:

1280×1024=1310720 pixels

So that the frame contained 1310720 pixels

The size of the frame buffer is equal to the product of RGB and frame pixels:

=3 × 1310720

=3932160 bytes

Gnoma [55]
      C = 2πr      Divide both sides by 2π
C/2π = r           Switch the sides to make it easier to read
       r = c / 2π
